The positions of four elements A, B, C and D in the modern periodic table are shown below. Which element is most likely to form an acidic oxide?
(a) A
(b) B
(b) C
(d) D
Answer
Metals form basic oxides and non-metals form acidic oxides .
In the periodic table,
- elements towards the left are metals
- whereas those towards the right are non metals
- and the last row is for noble gasses .
Among the given elements,
- A and B are metals and therefore form basic oxides
- D is a noble gas
- C is a non metal and forms acidic oxides.
Therefore, the correct option is (c) C
